This is an Invitation for Bids (IFB No. PW-0269) document package prepared by the City of Santa Cruz Public Works Department for the Santa Cruz Resource Recovery Facility Enclosed Flare Station Installation Project. The project involves the design, construction, and installation of a low-nitrogen oxide (NOx) enclosed flare station at the City's Resource Recovery Facility located at 605 Dimeo Lane, Santa Cruz, California. The scope of work includes construction of approximately 3,600 square feet of flare station infrastructure, installation of approximately 200 linear feet of landfill gas header pipe, condensate management and air pipelines, a 92-inch outer diameter by 420-foot tall flare stack with combustion air blower systems and gas handling equipment, trenching, electrical work, concrete foundations, structural steel installation, and a six-foot-high chain link fence with access gates. The mandatory pre-bid meeting is scheduled for February 23, 2026, at 10:00 a.m. at the project site. Questions and clarifications must be submitted by February 27, 2026, at 5:00 p.m. Sealed bids are due by March 10, 2026, at 2:00 p.m. local time and will be publicly opened and read at the Santa Cruz Public Works Department, 809 Center Street, Room 201. The project must be completed within 90 working days from the Notice to Proceed.

The engineer's estimate for this project is $635,000, and bidders must provide firm-fixed pricing with no escalation. Bid security of 10 percent of the proposal amount must accompany each bid submission. At contract award, the successful bidder must provide a performance bond equal to 100 percent of the contract price, a payment bond of 50 percent of the contract price, and a maintenance bond equal to 10 percent of the contract price, with the maintenance bond remaining in force for one year after official acceptance. Successful bidders must submit a minimum of three client references demonstrating relevant experience within the past five years, comply with prevailing wage requirements, maintain current California Department of Industrial Relations registration, and provide proof of insurance including Professional Liability, Commercial General Liability, Auto Liability, and Workers' Compensation coverage with minimum limits of $2,000,000 per occurrence for general liability and $1,000,000 for automobile liability. Liquidated damages of $1,000 per calendar day apply for failure to meet the 90 working day deadline. The solicitation does not identify specific set-aside designations for disadvantaged enterprises. All contractors must comply with the City's Living Wage Ordinance and prevailing wage requirements. The City reserves the right to reject any and all bids and will award the contract to the lowest responsible and responsive bidder.
